Problems solved by technology

At this time, although the risk of liquid leakage is reduced, the air entering the liquid cooling system will affect the cooling effect
[0004] In the positive pressure cold plate liquid cooling system, the leakage detection line is mainly used to detect the leakage of the coolant, while the negative pressure cooling system does not have the coolant leaking out of the pipeline, the leakage detection line cannot be used, and there is currently no negative pressure Technical solution for air leakage detection of liquid cooling system

Abstract

The invention provides a negative pressure liquid cooling system air leakage detection system, method and device. The system comprises a control module and a negative pressure liquid cooling circulation heat dissipation system. The control module is connected with a bubble sensor and an alarm module; and the negative pressure liquid cooling circulation heat dissipation system is arranged in the server, and a high-heat component in the server is attached to a pipeline of the negative pressure liquid cooling circulation heat dissipation system. The bubble sensor is arranged outside a pipeline of the negative pressure liquid cooling circulation heat dissipation system; the control module is also connected with the server; and the control module monitors the negative pressure liquid cooling circulation heat dissipation system in real time through the bubble sensor, judges whether a bubble signal exists in a pipeline of the negative pressure liquid cooling circulation heat dissipation system or not, and then judges whether air leakage alarm is conducted or not and controls the server to be shut down or not. The risk of liquid cooling failure caused by air leakage of the pipeline of the negative pressure liquid cooling system is greatly reduced, so that server downtime or chip overtemperature burnout is avoided, meanwhile, the missing report rate is reduced, and the reliability of the negative pressure liquid cooling system is improved.

Description

technical field [0001] The invention belongs to the technical field of server liquid cooling, and in particular relates to a negative pressure liquid cooling system air leakage detection system, method and device. Background technique [0002] As the power consumption of CPU, GPU and other components increases exponentially, the traditional air-cooling technology has reached its cost-effective heat dissipation limit, which can solve the problem of heat dissipation with higher heat flux density, and at the same time, liquid cooling technology with higher energy efficiency has emerged as the times require . Currently commonly used chip-level liquid cooling technologies include immersion liquid cooling and cold plate liquid cooling, but immersion liquid cooling has a small application scale due to high cost and difficult maintenance, while cold plate liquid cooling uses pumps to drive cooling fluids such as water and ethyl alcohol. Glycol, etc. flow through the channel on the ...
